All Aluminium Alloy Conductor AAAC Conductor ASTMB399
Application
Conductor AAAC has been widely used in transmission lines with various voltage levels,because they have such good characteristics as simple structure,convenient installation and maintenance,low cost large transmission capacity.And they are also suitable for laying across rivers valleys and the places where special geographical features exist.
Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a high-strength aluminum alloy to achieve a high strength-to-weight ratio; affords better sag characteristics. Aluminum alloy gives AAAC higher resistance to corrosion than ACSR.
Construction
Standard 6201-T81 high strength aluminum conductors, conforming to ASTM Specification B-399, are concentric-lay-stranded, similar in construction and appearance to 1350 grade aluminum conductors. They were developed to fill the need for an economical conductor for overhead applications requiring higher strength than that obtainable with 1350 grade aluminum conductors, but without a steel core. There are some common code that be used widely,such as Greely Conductor,AAAC Cairo,AAAC Azusa,AAAC Alton,AAAC Anaheim,and AAAC Alliance,you can find the detailed specification below:
Specification
AAAC bare conductor meets or exceeds the following ASTM specifications:
